Certain ETFs have wrong High value on intaday candles

We're closing the incident, while we'll proceed with the data cleanup. We're sorry for trouble. We're also working with our data provider to find out where these weird ticks have originated from.

We have resolved the root cause of the problem. We are now gradually correcting data, weeding out bad ticks. This procedure will be completed in 28 minutes.

We have found out that some ETFs (like SPY) have wrong wicks. Namely, wrong High values which are obviously abnormal. We're working to fix that asap.
